I had a gluster volume named data of distributed mode. I added a brick server1:/vdata/bricks/data to the volume data, However I found that vdata/bricks/data is on the / disk of linux. I wanna remove the brick from volume. So I use gluster volume remove disk data server1:/vdata/bricks/data start. Then I check the status using gluster volume remove-brick data server1:/vdata/bricks/data status but found the status is failed, and the scanned files is always 0. So what could I do to remove this brick without lossing data?
I have found the reason myself. It is because of DNS resolution failure for some server nodes. After I recovered the DNS, everything works OK!
